Glossary

■ Air Surround

Front surround sound system which is developed by
Yamaha enables the surround sound field. In comparison
with traditional front surround technologies, the Air
Surround system enables a wide range of natural surround
sound field.

■ Channel (ch)

A channel is an audio type that has been divided based on
range and other characteristics.
Ex. 5.1 channel

• Front speakers, Left (1ch), Right (1ch)

• Center speaker (1 ch)

• Surround speakers, Left (1ch), Right (1ch)

• Subwoofer (1 ch x 0.1* = 0.1 ch)

*

In contrast to a full 1-channel band, a component designed to
enhance low frequency sound for added effect.

■ CINEMA DSP
(Digital Sound Field Processor)

Since the Dolby Surround and DTS systems were
originally designed for use in movie theaters, their effect
is best felt in a theater having many speakers and designed
for acoustic effects. Since home conditions, such as room
size, wall material, number of speakers, and so on, can
differ so widely, it’s inevitable that there are differences in
the sound heard as well. Based on a wealth of actually
measured data, Yamaha CINEMA DSP uses Yamaha
original sound field technology to combine Dolby Pro
Logic, Dolby Digital and DTS systems to provide the
visual and audio experience of movie theater in the
listening room of your own home.

■ Dolby Pro Logic II

It is an improved matrix decoding technology that
provides better spatiality and directionality on Dolby
Surround programmed material; provides a convincing
three-dimensional sound field on conventional stereo
music recordings; and is ideally suited to bring the
surround experience to automotive sound. While
conventional surround programming is fully compatible
with Dolby Surround Pro Logic II decoders, soundtracks
will be able to be encoded specifically to take full
advantage of Pro Logic II playback, including separate left
and right surround channels.

■ DTS

Digital surround sound system developed by DTS, Inc.,
which provides 5.1 channel audio. With an abundance of
audio data, it is able to provide authentic-sounding effects.

■ PCM (Pulse Code Modulation)

A signal that is changed to digital format without
compression. A CD is recorded with 16-bit sound at 44.1
kHz, while DVD recording is anywhere from 16 bits at 48
kHz to 24 bits at 192 kHz, which makes it a higher quality
sound than CD.

■ Sampling frequency

The number of sampling (process for digitalizing analog
signals) per second. In principle, the higher the sampling
rate, the wider the frequency range that can be played
back, and the higher the quantized bit rate, the finer the
sound that can be reproduced.

■ Dolby Digital

Digital surround sound system which is developed by
Dolby Laboratories provides completely independent
multi-channel audio. With 3 front channels (left, center,
and right) and 2 surround stereo channels, Dolby Digital
provides five full-range audio channels. With an additional
channel especially for bass effects (called LFE, or low
frequency effect), the system has a total of 5.1-channels
(LFE is counted as 0.1 channel). By using 2-channel
